'Leave a comment' not working in Chateau v 2.0.2 (5 posts)

I'm a fellow newbie to wordpress and coding. I recently upgraded to the most recent Chateau template version 2.0.2 which is great but I'm having real problems changing the text in the comment box which currently says '0 comments' which I'd like to replace with 'Leave a comment'. I have tried everything and nothing seems to work. Any pointers in the right direction would be hugely appreciated thanks.

We do not support commercial themes as you paid for support when you bought the theme. It is not our place to keep theme vendors in business or deprive them of any income that they may derive from support services.
